Northwestern, central and south-central India are new hotspots of intense heatwave over the past 50 years, a study has said. The study also highlights the need for developing effective heat action plans in the three heatwave hotspot regions with a focus on different vulnerabilities among the inhabitants.
Heatwaves have emerged as a deadly health hazard, claiming thousands of lives across the globe in recent decades, with episodes strengthening in frequency, intensity and duration in the past half-century in India as well. This has caused severe impact on health, agriculture, economy and infrastructure.
In such a scenario, it is extremely important to identify the most heatwave vulnerable regions of the country to prioritise immediate policy intervention and stringent mitigation and adaptation strategies, the Department of Science and Technology (DST)said.
The team studied the change in spatial and temporal trends in Heatwaves (HW)…
